SAFETY INSPECTIONS AND MAINTENANCE I WARNING It is important to keep your wheelchair in proper working condition. Chapter 2 of this Manual outlines the safety inspections that you should make before each use of your chair, as well as weekly and quarterly inspections. 1. ALWAYS inspect and maintain your TiLite wheelchair strictly in accordance with the instructions and charts in Chapter 2. 2. If you detect a problem in the course of your inspections or maintenance, ALWAYS have the chair serviced or repaired to correct the problem BEFORE using the chair. 3. ALWAYS have your chair completely inspected and serviced by an authorized TiLite supplier at least once a year. 4. ALWAYS perform your safety inspections and any maintenance or adjustments while the chair is unoccupied (unless this Manual expressly states otherwise). If you fail to inspect or maintain your wheelchair as directed in this Manual, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. B. ACCLIMATING TO YOUR NEW CHAIR I WARNING Each wheelchair is a unique piece of medical equipment, with unique handling, maneuvering and ride characteristics. Whether you are a new wheelchair user or have years of experience, you MUST take the time to acclimate to this particular chair before you begin riding. Start slowly and take the time to learn the handling, maneuvering and ride characteristics of this chair. For example, your previous chair may have been a heavier and less responsive chair, and, therefore, you may be used to using more force than is necessary to maneuver your TiLite chair. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. C. WEIGHT LIMITATION I WARNING The TiLite Aero T and TRA wheelchairs have a weight limit of 265 pounds (120 kilograms). This weight limitation applies to the combined weight of the user and any items carried by the user. DO NOT exceed this weight limit. If you exceed the limit, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. D. PREVENTING ACCIDENTS AND INJURIES I WARNING 1. You MUST be properly and fully trained in the safe use of this wheelchair by your health care advisor BEFORE you use this chair. 2. Together with your health care advisor, you MUST analyze your level of function and ability and develop your own methods for safe use that best suit you based on your level of function and ability. 3. You MUST learn the limits of your ability and operate this wheelchair within such limits. This means you must PRACTICE the maneuvers you will need to perform, such as bending, reaching and transfers, until you know the limits of your ability. ALWAYS practice with the assistance of someone who can help you until you know what can cause, and how to avoid, a fall or tip-over. NEVER try a new maneuver on your own until you are sure you can do it safely. 4. ALWAYS learn as much as you can about the places where you will be using your chair before you get there. ALWAYS be alert for hazards and learn how to avoid them. 5. Anti-tips MUST be used with your wheelchair at all times. Because anti-tips are an option on this wheelchair, TiLite strongly recommends you order the anti-tips as they are an important safeguard for the wheelchair user. 6. Together with your health care advisor, you MUST analyze your medical condition to determine whether you are capable of using this chair safely and/or what options or accessories you will require in order to use this chair safely (e.g., pressure-relief cushions, seat belts). Aero T and TRA Owner’s Manual 1-1 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. E. CHANGING/ADJUSTING YOUR WHEELCHAIR I WARNING 1. Use extreme caution when changing or adjusting the configuration of your TiLite wheelchair. When you change or adjust the configuration, you may increase the risk of a tip-over. Therefore, you should consult your authorized TiLite dealer BEFORE you change or adjust the configuration. Further, TiLite recommends that you use anti-tips at all times, and this is particularly true after you have changed or adjusted the configuration of your chair. 2. Unauthorized modifications to your chair, or the use of parts not supplied or approved by TiLite, may change the chair structure, may cause a safety hazard, including an increased risk of a tip-over, and will void the warranty. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. F. ENVIRONMENTAL FACTORS I WARNING 1. Riding your TiLite wheelchair on wet, icy or other slick surfaces increases the risk of losing control of the wheelchair or tipping over. Use extra care if you must ride your chair on any such surface. If you have any doubt about your ability to negotiate a particular surface, ALWAYS ask for assistance. 2. Titanium does not rust or corrode. Aluminum does not rust, but it will corrode. However, contact with water or excess moisture may still damage parts or components of your TiLite wheelchair that are made from other materials and could cause such parts or components to fail. Therefore, DO NOT: a. use your chair in a shower, pool or other body of water, b. leave your chair in a damp location, or c. fail to dry your chair as soon as you can if it gets wet or if you use water to clean it. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. G. STREET USE I WARNING 1. As a wheelchair rider, you MUST obey all traffic rules pertaining to pedestrians (use of crosswalks, etc.). Most states do not permit wheelchairs to be ridden on public roads, streets or highways (i.e., as one would drive a car), so you should not do so without first consulting the traffic laws in your own state. Even if legal, riding your wheelchair on public roads, streets or highways is extremely dangerous and is not recommended. 2. At all times when riding your wheelchair in public areas (sidewalks, crosswalks, parking lots, etc.), be very alert to the danger of motor vehicles. 3. At night, or when lighting is poor, use reflective tape on your chair and clothing. 4. Due to your low position, it may be hard for drivers to see you. This is particularly true in situations where drivers may be driving in reverse, such as parking lots. If at all possible, make eye contact with drivers before you go forward. When in doubt, yield until you are sure it is safe, even if you have the right-of-way. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. H. TERRAIN I WARNING Your TiLite wheelchair is designed for riding over firm, relatively smooth surfaces such as concrete and asphalt outdoors and indoor flooring (wood, tile, etc.) and carpeting. Your TiLite wheelchair is NOT designed for riding over sand, loose soil or rough terrain. Do NOT operate your chair in such terrain. You may damage the wheels or axles or loosen fasteners of your chair. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Aero T and TRA Owner’s Manual 1-2 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS I. MOTOR VEHICLE SAFETY I WARNING TiLite wheelchairs are NOT designed to be used for seating in a motor vehicle, and TiLite wheelchairs do NOT meet Federal standards for motor vehicle seating. 1. NEVER sit in your chair while in any type of moving vehicle (bus, automobile, van, truck, boat, train, etc.). In an accident or sudden stop, you may be thrown from the chair. In an accident or sudden stop, a wheelchair seat belt will NOT prevent injuries and may, in fact, cause injuries. 2. ALWAYS transfer to an approved vehicle seat before the vehicle begins moving. 3. ALWAYS secure yourself in the approved vehicle seat using the proper seating restraints (in a motor vehicle, lap/ shoulder belts; in a plane, lap belts, etc.). 4. NEVER transport your chair in the front seat of a vehicle. Movements of the vehicle may cause the chair to shift and interfere with the driver’s ability to control the vehicle. 5. When transporting your chair in a moving vehicle, ALWAYS secure your chair so that it cannot roll or shift. In most cases, stowing it in the trunk is the safest alternative. 6. NEVER use any chair that has been involved in a motor vehicle accident. A wheelchair that has been involved in a motor vehicle accident may be damaged in ways that are not readily apparent and which could cause the chair to fail in use. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. J. WEIGHT TRAINING I WARNING NEVER use your TiLite wheelchair for weight training. When your chair was set up with the assistance of your health care advisor, your center of gravity was determined based on your weight, the configuration of your chair and your abilities. If you engage in weight training activities in your chair, you are altering the total weight supported by your chair and the distribution of that weight. The center of gravity of your chair may not be appropriate with the additional weight or with the different distribution of weight, which may cause the chair to tip over. The additional weight could exceed the weight limit for the chair and damage the chair. If you intend to engage in weight training, TiLite recommends that you utilize weight training equipment with built-in seating and that you transfer to that seating rather than using your chair. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. K. OBTAINING ASSISTANCE I WARNING For The Wheelchair User: ALWAYS make sure that each person who assists you reads and understands this entire Manual, especially the Warnings in Chapter 1. For Attendants/Assistants: 1. ALWAYS work with the user’s health care advisor to learn safe methods to assist the wheelchair user and to determine which methods are best suited to your abilities and those of the user. 2. ALWAYS communicate to the user what you plan to do before you do it and explain what you expect the user to do while you are taking such action. This will put the user at ease and reduce the risk of an accident due to a miscommunication. 3. ALWAYS use good posture and proper body mechanics in order to avoid injury to your back. 4. When you lift or support the user or tilt the chair, ALWAYS bend your knees slightly and keep your back as upright and straight as you can. 5. Wheelchair push handles are designed to provide a secure location for an attendant to grip the rear of the wheelchair to prevent a fall or tip-over. ALWAYS make sure the wheelchair has push handles and ALWAYS use them. REGULARLY check to make sure the push handle grips are securely seated on the back canes so they will not rotate or slip off. Aero T and TRA Owner’s Manual 1-3 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 6. If you are going to tilt the chair backward, ALWAYS remind the user to lean back. 7. If you are going to descend a curb or single step, ALWAYS lower the chair slowly in one easy movement. NEVER let the chair drop the last few inches to the ground. This may damage the chair or injure the user. 8. ALWAYS become familiar with the user’s wheelchair and all of its parts and components. In particular, be very aware of any removable parts. Removable parts must NEVER be used for a hand-hold or lifting supports because they may inadvertently release, resulting in possible injury to the user and/or assistant. 9. Anti-tips may present a tripping hazard to the attendant. To avoid tripping over the anti-tips, unlock and rotate antitip tubes up, out of the way. However, if you must leave the user unattended, even for a moment, ALWAYS rotate the anti-tips back into the down position and lock the rear wheels using the wheel locks. This will reduce the risk of a tip-over or loss of control of the chair. 10. When you are learning a new assistance technique, ALWAYS have an experienced attendant help you before attempting it on your own. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. L. STANDING ON YOUR CHAIR I WARNING Your TiLite wheelchair has been designed for use as a wheelchair, not as a step ladder. NEVER stand on your TiLite wheelchair. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. WARNINGS FOR SAFE USE OF YOUR WHEELCHAIR A. LEARNING TO DO A “WHEELIE” I WARNING DO NOT attempt to perform a “wheelie” in your wheelchair because of the dangerous nature of this kind of maneuver. TiLite recognizes that some wheelchair users will ignore this warning. If you should choose to ignore this warning, you should follow these steps to help learn to do a “wheelie” as safely as possible (but doing a “wheelie” is never completely safe and TiLite assumes no responsibility for any injury you may sustain as a result of doing a “wheelie”): 1. Read and follow the Warning for “WHEELIES” on page 1-9. 2. NEVER attempt to learn how to do a “wheelie” without the assistance of someone strong enough to catch you should you start to tip over (a “spotter”). Your spotter should read and be completely familiar with this entire Manual, especially this Warning and the Warning for “WHEELIES” on page 1-9. 3. Instruct your spotter to stand at the rear of your chair. Your spotter must be agile enough to move with you and your chair to prevent a tip-over. 4. Instruct your spotter to keep his or her hands BENEATH the push handles or backrest rigidizer bar so that he or she is ready to catch you if you exceed the balance point of the rear wheels and start to tip over backward. 5. When your spotter is in position and is ready, place your hands on the forward portion of the handrims. Using the handrims, make a quick BACKWARD movement of the rear wheels, quickly followed by a hard FORWARD thrust. This will tilt the chair up on the balance point of the rear wheels. DO NOT remove your hands from the handrims after either the backward movement or forward thrust so that you can continue to manipulate the rear wheels to maintain your balance on the two rear wheels. 6. Use SMALL movements of the handrims to maintain your balance on the two rear wheels. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Aero T and TRA Owner’s Manual 1-4 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS B. CLIMBING A CURB OR SINGLE STEP I WARNING 1. NEVER attempt to negotiate a curb or single step without assistance. 2. Instruct your assistant to stand at the rear of your wheelchair, with the front of the wheelchair facing the obstacle. NEVER attempt to negotiate any such obstacle backward. 3. Instruct your assistant to tilt the chair up on the rear wheels so that the front casters clear the curb or step. 4. Instruct your assistant to slowly move the chair forward and to gently lower the front casters to the upper level as soon as you are sure that they are beyond the edge of the curb or step. 5. Instruct your assistant to continue to roll the chair forward until the rear wheels contact the face of the curb or step. 6. Instruct your assistant to lift and roll the rear wheels up to the upper level. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. C. CLIMBING A FLIGHT OF STAIRS I WARNING DO NOT climb a flight of stairs with the user in the wheelchair. However, TiLite recognizes that wheelchair users may, on occasion, have no other choice. Only if you have no alternative, you should follow these steps to climb up a flight of stairs. 1. NEVER attempt to negotiate more than one step unless you have two (2) able-bodied adult assistants. 2. ALWAYS position the chair and rider facing away from the stairs, with one assistant at the rear (facing away from the stairs) and one at the front of the chair (facing the rider). 3. The assistant at the rear of the chair is in control of this procedure. He or she must tilt the chair back to its balance point on the rear wheels. NEVER attempt to lift a wheelchair by lifting on any removable (detachable) parts, including upholstery and removable push handles or push handle grips. 4. The second assistant at the front must firmly grasp a non-detachable part of the front frame (but NOT swing-away hangers) with both hands and lift the chair up and over one stair at a time. 5. Each assistant then carefully moves up to the next stair. 6. Repeat steps 1 through 5 for each stair, until you reach the landing. 7. When you reach the landing, the assistants should roll the chair backward on the two rear wheels until the front casters have cleared the last step, at which point the assistants can gently lower the front casters to the landing. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. D. DESCENDING A CURB OR SINGLE STEP I WARNING 1. NEVER attempt to negotiate a curb or single step without assistance. 2. When you are still several feet from the edge of the curb or step, instruct your assistant to stand at the rear of your wheelchair and turn it around so you are facing AWAY from the obstacle. 3. NEVER attempt to negotiate any such obstacle facing forward. 4. Instruct your assistant to carefully step backwards, pulling the chair backwards, until he or she is off the curb or stair and standing on the lower level. The assistant should watch his or her step over his or her shoulder when backing up in this manner. 5. Instruct your assistant to carefully pull the chair backward until the rear wheels reach the edge of the curb or step, and to then allow the rear wheels to slowly roll down to the lower level. 6. Instruct your assistant that, when the rear wheels are safely on the lower level, he or she may then tilt the chair backward to the balance point of the rear wheels, thereby raising the front casters off the upper level. 7. Instruct your assistant to slowly roll the chair backward on the rear wheels, taking small steps until the front casters have cleared the step or curb and, when clear, to gently lower the front casters to the ground at the lower level. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Aero T and TRA Owner’s Manual 1-5 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS E. DESCENDING A FLIGHT OF STAIRS I WARNING DO NOT descend a flight of stairs with the user in the wheelchair. However, TiLite recognizes that wheelchair users may, on occasion, have no other choice. Only if you have no alternative, you should follow these steps to descend a flight of stairs. 1. NEVER attempt to negotiate more than one step unless you have two (2) able-bodied adult assistants. 2. ALWAYS position the chair and rider facing down the stairs, with one assistant at the rear (facing down the stairs) and one at the front of the chair (facing the rider). 3. The assistant at the rear of the chair is in control of this procedure. He or she must tilt the chair back to its balance point on the rear wheels and roll it to the edge of the first step. NEVER attempt to lift a wheelchair by lifting on any removable (detachable) parts, including upholstery and removable push handles or push handle grips. 4. The second assistant at the front must stand at the third step from the top and firmly grasp a non-detachable part of the front frame (but NOT swing-away hangers) with both hands. The second assistant must lower the chair one stair at a time by letting the rear wheels roll over the stair edge. Each assistant then carefully moves down to the next stair. 5. Repeat steps 1 through 4 for each stair, until you reach the ground level. 6. When you reach the ground level, the first assistant should carefully lower the front casters to the ground. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. WARNINGS REGARDING FALLING AND TIPPING OVER A. CENTER OF GRAVITY—STABILITY AND BALANCE I WARNING Most falls or tip-overs occur when you go beyond the center of gravity of you and your wheelchair. TiLite wheelchairs are designed to remain stable and upright in normal daily use and activities so long as you do not exceed the center of gravity. Every movement you make in your chair, and the rapidity with which you move, will have an affect on your center of gravity. The more you shift your body weight and the greater the speed at which you shift it, the greater the impact on your center of gravity in your chair. There is a point where your wheelchair will tip forward or backward or to the side—which is a function of your center of gravity in the chair—its center of balance and stability. The type of chair, the setup of your chair, the options on your chair and the changes you make to the setup or options will all affect the center of gravity and therefore the stability of the chair. As the stability decreases, the risk of a fall or tip-over increases. Set forth below is a list of various types of adjustments that you may be able to make to your wheelchair, depending on the wheelchair model you own, and a brief description of how those adjustments will affect your center of gravity: 1. The position of the rear wheels is the most significant factor affecting your center of gravity. The more you move the rear wheels forward, the more likely your chair will tip over backward. 2. The distance between the rear wheels. The less distance between the rear wheels, the greater the likelihood your chair will tip over to the side. 3. The amount of rear wheel camber. The less camber, the greater the likelihood your chair will tip over to the side. Aero T and TRA Owner’s Manual 1-6 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 4. The height of your seat. As you raise the height of your seat, you raise your center of gravity and increase the likelihood of all types of tip-overs. 5. The angle of your seat. As you increase the angle of your seat (relative to the floor), your position in the chair is shifted toward the rear of the chair, increasing the likelihood your chair will tip over backward. 6. The angle of your backrest. As you increase the angle of your backrest (relative to the seat), your position in the chair is shifted toward the rear of the chair, increasing the likelihood your chair will tip over backward. 7. The height of your seat back. As you lower the height of your seat back, you make it easier to lean back in your chair, which in turn shifts your center of gravity rearward and increases the likelihood your chair will tip over backward. 8. The position of your front casters. As you move your front casters rearward on the frame (toward the rear wheels), you increase the likelihood your chair will tip over forward. Other factors will affect your center of gravity: 1. A change in your body position, posture or weight distribution. For example, if you lean forward you shift the center of gravity forward and increase the likelihood of tipping over forward. 2. Riding your chair on a ramp or slope. On an up-slope, your weight shifts to the rear and a backward tip-over becomes more likely. On a down-slope, your weight shifts to the front of the chair and a forward tip-over becomes more likely. 3. The use of a backpack or other options, and the amount of weight added by those options. For example, carrying a lot of weight in a backpack will shift the center of gravity rearward and increase the likelihood of tipping over backward. However, using a TiLite seat pouch beneath the seat sling to carry heavier items will lower your center of gravity and reduce, but not eliminate, your risk of a tip over. In order to reduce the risk of a tip-over, you should: 1. CONSULT your doctor, nurse or therapist to find out what axle and caster position and other chair configuration options are best for you. 2. CONSULT your authorized TiLite dealer BEFORE you modify or adjust your wheelchair. Often, an adjustment you wish to make can be offset by another that you have not considered. For example, you may want to adjust the back angle rearward, which will increase the likelihood of a rear tip-over. You might not think you could counteract this tendency by moving the rear wheels backward. Your authorized TiLite dealer will be able to give you expert, personalized advice in such matters. See “Changing/Adjusting Your Wheelchair” on page 1-2. 3. ALWAYS have someone assist you until you learn your chair’s balance points and are completely comfortable in your ability to operate your chair under all conditions so as to avoid tip-overs. 4. ALWAYS use anti-tips. See “Changing/Adjusting Your Wheel Chair” on page 1-2. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. B. TRANSFERRING IN AND OUT OF YOUR WHEELCHAIR I WARNING Transferring in or out of your wheelchair is one of the most dangerous things you can attempt relating to your wheelchair. It requires good balance, agility and upper body conditioning. At some point in every transfer, there is no wheelchair seat beneath you and the seat, bed, etc. to or from which you are transferring is not beneath you either. Important rules that will help to reduce the risk of a fall during a transfer are discussed below: 1. ALWAYS work with your health care advisor to learn safe transfer methods. 2. ALWAYS ask your health care advisor to teach you proper body positioning during a transfer and how to support yourself during a transfer. 3. ALWAYS have someone assist you when you transfer until you have learned how to transfer safely and have developed the upper body strength and coordination to transfer safely. 4. ALWAYS move your chair as close as you can to the seat (bed, etc.) to which you are transferring. If possible, use a transfer board. Aero T and TRA Owner’s Manual 1-7 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 5. ALWAYS lock the rear wheels using wheel locks before you transfer. This keeps the rear wheels from rolling. If your wheelchair is equipped with caster pin locks, ALWAYS lock them before you transfer. Caster pin locks keep the front casters from rotating (but not from rolling). NOTE: Wheel locks and caster pin locks will NOT keep your chair from sliding away from you or tipping. 6. If your wheels have pneumatic (inflatable) tires, ALWAYS make sure to keep the tires properly inflated at all times. The wheel locks may slip if the tire pressure is low, which may cause the chair to roll unexpectedly during a transfer. 7. ALWAYS rotate the front casters as far forward as possible and turn them to the seat (bed, etc.) to which you are transferring. 8. ALWAYS remove the wheelchair armrests, or swing them out of the way, so they do not impede your movement during the transfer. 9. If possible, ALWAYS remove the footrests, or swing them out of the way, to ensure your feet do not get caught between the footrests. TiLite strongly recommends that you place your feet on the floor when you are transferring to or from your chair. 10. NEVER put your weight on the footrests when you are transferring to or from your chair because this may cause the chair to tip over and/or roll away. 11. When transferring into your chair, ALWAYS transfer as far back onto your seat as possible in order to reduce the risk that the chair will tip over or move away from you causing you to fall. 12. If possible, ALWAYS try to avoid falling into your chair uncontrollably when transferring into your chair. This places undue stress on your chair’s components, and if your chair does start to move or tip you will not be ready to regain control. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. C. DRESSING/UNDRESSING IN YOUR CHAIR I WARNING When you engage in activities while seated in your chair such as dressing or undressing or changing your clothes, your weight will shift. Since your attention will be directed to the activity in question, your risk of falling or tipping over is increased. To reduce this risk, get dressed or undressed or change your clothes while seated in a regular chair or on a bed. If you must get dressed or undressed or change your clothes while seated in your wheelchair: 1. ALWAYS rotate the front casters so they are trailing forward. This makes the chair more stable. NOTE: To get your front casters to trail forward, first move your chair forward and, second, back up. By moving backward, your front casters will rotate and trail forward. 2. ALWAYS lock your anti-tips in the down position so the risk of a backward tip-over is minimized. If your chair does not have anti-tips, back it up against a wall and lock both rear wheels using your wheel locks. 3. If your chair is equipped with caster pin locks, ALWAYS engage them. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. D. BENDING/LEANING/REACHING I WARNING When you bend, reach or lean from your chair you will affect the center of balance of your chair. Therefore, bending, reaching or leaning may cause you to fall or tip over. In order to avoid falling or tipping over, you must determine your particular safety limitations given the configuration of your chair and your body weight and type. To do this, practice bending, reaching and leaning activities (and various combinations of such activities) under the supervision of your health care advisor. Do this BEFORE attempting active use of your chair. The following will help you avoid falling or tipping over when bending, reaching or leaning from your chair: 1. NEVER bend, reach or lean in a way that requires you to move forward in your seat. 2. ALWAYS keep your buttocks in contact with the backrest and the seat cushion when bending, reaching or leaning. 3. NEVER shift your weight in the same direction you are bending, reaching or leaning. 4. NEVER reach or lean to the rear unless your chair has anti-tips locked in place. Aero T and TRA Owner’s Manual 1-8 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 5. NEVER reach with both hands. By keeping one hand free, you may be able to catch yourself to prevent a fall if the chair starts to tip. 6. NEVER reach or lean over the top of the seat back. If you do so you may damage the seat back tubes, which could cause you to fall. 7. ALWAYS move your chair as close as possible to the object you are trying to reach. 8. NEVER shift your weight to the footrests. 9. NEVER try to pick up an object from the floor by reaching down between your knees. You are less likely to tip over if you reach to the side of your chair when picking up an object on the floor. 10. DO NOT lock the rear wheels when bending, reaching or leaning backward. Locking the rear wheels creates a tip point and makes falling or tipping over more likely. 11. When bending or leaning, ALWAYS grasp one rear wheel with one hand. This will help to prevent a fall if the chair starts to tip over. 12. ALWAYS rotate the front casters until they are trailing forward. This will make the chair more stable. NOTE: To get your front casters to trail forward, first move your chair forward past the object you want to reach and, second, back up alongside the object. By moving backward, your front casters will rotate and trail forward. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. E. MOVING BACKWARD I WARNING When you propel backward, you will tend to shift your weight backward, making a tip-over more likely. In addition, you may be unable to see an obstruction that could block one of your wheels and cause a tip-over. Therefore, use extreme caution when propelling backward. If you must propel backward: 1. ALWAYS propel slowly with smooth, short strokes. 2. MAKE frequent stops to check for obstructions in your path. 3. If your chair has anti-tips, ALWAYS make sure to lock them in place. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. F. WHEELIES I WARNING Balancing in your chair on just the rear wheels with the front casters in the air is known as doing a “wheelie.” DOING A WHEELIE IS DANGEROUS. A fall or tip-over is very likely. However, if you can do a “wheelie” safely, you may be able to overcome curbs and obstacles that would otherwise impede you. NEVER attempt to learn to do a “wheelie” without first consulting your health care advisor to make sure you are a good candidate to learn to do a “wheelie.” NEVER attempt to learn to do a “wheelie” without an assistant that can catch you if you should happen to start to fall. NEVER attempt to learn to do a “wheelie” unless you are a skilled rider of this chair. See “Learning to do a ‘Wheelie’” on page 1-4. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. G. OBSTACLES I WARNING When riding outdoors, uneven pavement, sidewalk irregularities, potholes and other obstacles and road hazards can be dangerous. When riding indoors, doorway thresholds, plush carpeting and other obstacles can be dangerous. In order to avoid these risks: 1. ALWAYS be alert for such dangers. 2. ALWAYS scan the area ahead of you as you ride. 3. REMOVE or cover threshold strips between rooms. Aero T and TRA Owner’s Manual 1-9 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 4. INSTALL ramps at entry or exit doors from your residence. Make sure the transition from such ramps to the pavement or other surface is smooth and does not have an abrupt drop-off. 5. ALWAYS make sure the floors where you live and work are level. 6. KEEP all floors where you live and work free of obstacles and hazards. 7. When riding UP and over an obstacle, lean your upper body slightly FORWARD. 8. When riding DOWN from a higher to a lower level, press your upper body BACKWARD lightly. 9. ALWAYS keep both hands on the handrims as you go over an obstacle. 10. NEVER push or pull on any object, such as a door knob or door jamb or furniture, in order to propel your chair. 11. If your chair has anti-tips, lock them in place before you go UP over an obstacle. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. H. CURBS/STEPS I WARNING Curbs and steps are extremely dangerous obstacles. 1. NEVER attempt to go up or down a single curb or step without an assistant UNLESS: a. you are a very skilled rider of your chair; and b. you have previously learned to safely do a “wheelie” in your chair; and c. you are sure you have the strength and balance to control your chair during any such maneuver. 2. ALWAYS unlock and rotate anti-tips up and out of the way so they do not prevent you from executing this maneuver. 3. Even if you are a highly skilled rider, NEVER attempt to climb or descend a curb or step more than 4” high. 4. ALWAYS go straight up or down a curb or step. NEVER climb or descend at an angle. 5. ALWAYS be aware that the impact of dropping down from a curb or step can damage your chair or cause components to become loose. If you perform such maneuvers, inspect your chair more frequently. If you are not highly skilled at tilting the chair, or the step or the curb is more than 4” high, ALWAYS have an assistant help you negotiate curbs and steps. Your assistant must first read the Warnings contained in this Manual in their entirety, especially the sections titled “Climbing a Curb or Single Step”, “Climbing a Flight of Stairs”, “Descending a Curb or Single Step” and “Descending a Flight of Stairs” on pages 1-4 to 1-6. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. I. HILLS/SLOPES/RAMPS I WARNING The center of balance of your chair is affected by the slope of the surface over which you are riding. Because your center of balance will be affected, your chair will be less stable when it is at an angle. This is especially true when riding on a slope sideways. Furthermore, do not assume anti-tips will prevent a fall or tip-over under these conditions. The following rules may help to avoid a fall or tip-over: 1. ALWAYS go up or down a slope, hill or ramp as straight as possible. If you try to cut the corner, you will be traversing the slope, hill or ramp sideways to the slope and your risk of tipping over sideways will increase. 2. NEVER use your chair on a slope greater than 10%—a slope with an elevation greater than one foot in height for every ten feet in length. 3. NEVER stop on a steep slope. If you stop on a steep slope, you may not be able to maintain control of the chair. 4. NEVER use rear wheel locks as a brake to slow or stop your chair. Wheel locks are NOT brakes. Doing so will most likely cause the chair to veer out of control. 5. NEVER try to turn around or change direction when going up or down a slope. 6. ALWAYS stay in the CENTER of a ramp. 7. NEVER start up or down a ramp unless you are certain the ramp is wide enough for its entire length so your wheels will not fall off the edge. 8. In order to control your speed, ALWAYS keep pressure with your hands on the handrims when going down a hill, slope or ramp. DO NOT go too fast. Excessive speed may cause you to lose control of your chair, or it may cause your casters to flutter which can cause a fall or tip-over. Aero T and TRA Owner’s Manual 1-10 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS 9. ALWAYS lean or press your body in the UPHILL direction. This will help shift your weight to counteract the change in the center of balance caused by the hill, slope or ramp. 10. ALWAYS ask for assistance if you have any concerns at all about your ability to maintain safe control of your chair on a hill, slope or ramp. 11. ALWAYS be alert for wet or slippery conditions or surfaces, any changes in the grade of the slope (such as a lip, bump or depression), and any drop-off or lip at the bottom of a slope. For example, even a 3/4 inch lip at the bottom of a ramp can cause the front casters to stop and cause the chair to tip forward. 12. Ramps at your home and work must meet all legal requirements for your area, including building codes. If you are having a ramp installed at your home or work, ALWAYS make sure it complies with local legal requirements. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. J. STAIRS I WARNING NEVER use your wheelchair on stairs without the assistance of at least two (2) able-bodied assistants or attendants and ONLY AFTER such assistants or attendants have read and understand the Warnings “Climbing a Flight of Stairs” and “Descending a Flight of Stairs” on pages 1-5 to 1-6. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. K. ESCALATORS I WARNING NEVER use your wheelchair on an escalator, not even with an assistant or attendant. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. L. ASSISTANTS AND ATTENDANTS I WARNING Before you permit any person to assist you in any aspect of riding your wheelchair, you MUST require that the assistant or attendant fully read, understand and follow the Warnings contained in this Manual. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. WARNINGS REGARDING COMPONENTS AND OPTIONS A. ANTI-TIPS I WARNING Anti-tips are an optional accessory that can help to prevent your chair from tipping over backward. However, even the use of anti-tips will not guarantee that your chair will not tip over backward. Also, they will not prevent your chair from tipping over sideways or forward. TiLite strongly recommends you use anti-tips with your wheelchair. This is most especially true: a. if you are a new wheelchair rider; or b. even if you are an experienced rider but you are switching to a new wheelchair, regardless of whether the prior chair was as lightweight as your TiLite; or c. even if you are an experienced rider in your TiLite chair but you have made any modifications or adjustments to the configuration of your chair, such as changing the position of the front or rear wheels, changing the seat height, changing the camber or changing the seat or back angle. Any modification or change to Aero T and TRA Owner’s Manual 1-11 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS your chair can make it easier to tip over and you should use anti-tips until you have adapted to the modified configuration; or d. even if you are an experienced rider in your TiLite chair but your physical condition has changed. In order to properly use your anti-tips, please follow the following rules: 1. Your anti-tips should be between 1-1/2 inches to 2 inches off the ground when they are locked in place in the “down” position. 2. If your anti-tips are set too LOW, they may “catch” on obstacles that you can expect to encounter in normal wheelchair use. If this happens, you may tip over and fall. 3. If your anti-tips are set too HIGH, their ability to prevent a backward tip-over will be limited and they may not prevent a tip-over at all. 4. ALWAYS keep your anti-tips locked in place in the “down” position unless: a. You have an attendant (but your attendant must rotate the anti-tips into the “down” position whenever he or she leaves you unattended in your chair, even for a moment), or b. You have to climb or descend a curb or step or overcome an obstacle. Even if this is the case, only unlock the anti-tips if you can safely climb or descend the curb or step or overcome the obstacle and make sure the anti-tips are locked in the “up” position. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. B. SEAT SLINGS/CUSHIONS I WARNING TiLite seat slings (which are standard equipment) and cushions (which are optional equipment) are not designed for the relief of pressure. If you have pressure sores, or are at risk to get them, you may need a special pressure-relieving cushion or other seating system. If you have pressure sores, consult with your doctor immediately. If you are at risk to develop pressure sores or do not know if you are at risk, consult with your doctor as to the most appropriate seating system for you. TiLite has NO information about your medical condition and assumes no responsibility should you choose the wrong seating system for your medical needs. You MUST regularly check your seat sling while you are seated in your wheelchair to ensure that the tension is properly adjusted so that your weight does not cause the seat sling to touch the cross tubes beneath the seat sling. TiLite also offers a limited number of seat cushions manufactured by other manufacturers. However, the selection of any of these products is a decision to be made by you and your doctor or therapist. TiLite has NO information about your medical condition and assumes no responsibility should you choose the wrong seating system for your medical needs. If you ignore these Warnings, you may develop pressure sores, which can be a life-threatening complication from wheelchair use. C. UPHOLSTERY FABRIC I WARNING 1. If the fabric of your seat sling or seat back becomes worn or torn, ALWAYS replace it immediately. If you fail to do so, the seat sling or seat back upholstery may sag or fail. 2. The upholstery on your chair is flame retardant. Laundering or allowing the upholstery to become wet repeatedly will reduce the flame retardant qualities of the fabric. 3. DO NOT “drop down” into your chair. By placing undue force on the upholstery, you will weaken the fabric and it may become worn sooner than it otherwise would. If you do “drop down” into your chair on a regular basis, inspect and replace the upholstery more often. 4. The upholstery on your chair will weaken with age and use. Regularly inspect your upholstery for fraying, thin spots, or stretching of the fabric at the rivet holes. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Aero T and TRA Owner’s Manual 1-12 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS D. SEATING SYSTEMS I WARNING TiLite does not sell any seating systems specifically designed for use with TiLite wheelchairs, nor does TiLite recommend any particular seating system. If your doctor or therapist recommends that you use a seating system with your TiLite chair, always consult with an authorized TiLite dealer to determine if the recommended seating system is compatible with your TiLite chair. In addition, the following warnings must be followed: 1. If you add a seating system to your TiLite chair, you will affect its center of balance. This may cause the chair to tip over. Therefore, NEVER install a new seating system on your own. Instead, have it installed by an authorized TiLite dealer who can assist you in making other necessary adjustments to ensure your center of balance is maintained as closely as possible to what you are used to. 2. As with other changes to the configuration of your chair that affect its center of balance, if you add a seating system to your TiLite chair, ALWAYS use anti-tips until you have fully learned to control your chair in its new configuration. 3. Keep in mind that adding a seating system also may inhibit the proper operation of a folding back wheelchair. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. E. POSITIONING OR SEAT BELTS I WARNING TiLite hook & loop, non-padded seat belts and Bodypoint® non-padded hip belts, both of which are optional equipment, are intended ONLY for use as a positioning aid for simple positioning needs, such as posterior pelvic tilt. These belts will not be sufficient for persons with more involved positioning needs. Only your health care advisor can determine the proper positioning products for your situation. If used improperly, positioning or seat belts can cause severe injury or even death. If your health care advisor has instructed you to use positioning or seat belts, make sure they instruct you on the proper usage of such belts, and such professional should supervise your use of such belts to ensure you can use them safely. 1. Belts must fit snugly in order to work properly. However, they must not be so snug they interfere with your breathing. Your health care advisor should be able to slide his or her open hand flat between the belt and your body. 2. Make sure you do not slide down in your chair while wearing a belt. If this should happen, you may suffer chest compression or be suffocated due to pressure from the belt. 3. Do not use a positioning or seat belt unless you are capable of removing the belts easily in an emergency. If you cannot do this, consult with your health care advisor for other options to help with your posture. 4. There are devices that help to keep you from sliding down in the seat of your wheelchair, such as a pelvic wedge. Consult with your health care advisor to find out if you need to use such a device in conjunction with positioning or seat belts to mitigate the risks described above. 5. NEVER use positioning or seat belts as a motor vehicle restraint. These types of belts are NOT intended to protect the wheelchair rider from the forces involved in a vehicle accident, and they may, in fact, cause you to be injured. TiLite recommends wheelchair users ALWAYS transfer to appropriate motor vehicle seating when traveling in a motor vehicle. Note to Attendants/Assistants: NEVER use positioning or seat belts as a patient restraint (a restraint requires a doctor’s order) or on a wheelchair user who is comatose or agitated. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. F. ARMRESTS I WARNING Armrests are optional equipment on TiLite wheelchairs. TiLite armrests are detachable and are not designed to support the weight of your wheelchair. Therefore, NEVER lift your chair by its armrests. If you do, they may detach, causing you to drop the chair, or you may break the armrests or cause them to become loose and break at a later Aero T and TRA Owner’s Manual 1-13 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS time unexpectedly. ALWAYS lift your chair by grasping the non-detachable parts of the main frame (not including the swing-away hangers or backrests). If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. G. FOOTRESTS/HANGERS I WARNING Certain footrests are standard equipment with TiLite wheelchairs. Other, more specialized footrests are optional equipment. The following rules apply to footrests: 1. ALWAYS allow for AT LEAST 2 inches of clearance between the ground and the lowest point on the underside of your footrests. If you set your footrests too LOW, they may “catch” on obstacles you can expect to find in normal use of your chair. If your footrests “catch,” the chair may stop and tip forward. 2. NEVER lift your wheelchair by grasping the footrests or the swing-away hangers. Footrests and swing-away hangers are detachable and are not designed to support the weight of your chair. If you do, the footrests or the swing-away hangers may detach, causing you to drop the chair, or you may break the footrests or the swing-away hangers or cause them to become loose and break at a later time unexpectedly. 3. READ and understand the warnings under “Transferring In and Out of Your Wheelchair” on pages 1-7 to 1-8 of this Manual. There is important information in that section regarding your footrests and transfers. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. H. REAR WHEELS I WARNING Rear wheels are standard components on your wheelchair. The positioning of the rear wheels is a critical factor in locating the center of balance of your chair. Any change to your rear wheel position will change your center of balance. Therefore, use extreme caution when making any adjustment to the position of your rear wheels. 1. As you move the rear wheels and axles forward on your chair, you shift the center of balance FORWARD. This means it is easier for your chair to tip over backward. 2. As you move the rear wheels and axles backward on your chair, you shift the center of balance BACKWARD. This means your chair is less likely to tip-over backward. However, even if your rear wheels and axles are set as far back as possible, the chair can still tip-over backward. 3. ALWAYS consult with your health care provider to determine the best rear wheel/axle setup for you based on your weight and body type and your abilities to control the chair. 4. Once you and your health care provider have determined the best rear wheel/axle setup for you, NEVER change the setup UNLESS you are sure you are not at risk to tip over. 5. If you do change the rear wheel/axle position, you MUST adjust the positioning of the rear wheel locks to ensure they work properly to lock the rear wheels. When relocating the rear wheel locks, make sure the locking arm indents the tire by at least 3/16” when the wheel lock is in the “locked” position. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. I. AXLES I WARNING Stainless quick-release axles are a standard TiLite wheelchair component. Other axle types are optional equipment. All TiLite axles are designed to make your rear wheels easy to remove quickly. However, if not used properly, they can be dangerous. NEVER use your chair UNLESS you are sure that both rear axles are locked into place in the axle receiver. If an axle is not fully locked into place, the rear wheel may come off during use of the chair and cause you to fall. You can tell when the axle is locked into place because the quick-release button in the center of the axle will pop out fully. It is also Aero T and TRA Owner’s Manual 1-14 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS a good idea to pull on the wheel to double-check that the axle is securely locked as a final precaution. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. J. PNEUMATIC TIRES I WARNING Pneumatic rear tires are standard components on TiLite wheelchairs. Pneumatic front tires are optional equipment on some TiLite wheelchairs. With pneumatic tires, it is important to maintain the proper inflation. Maintaining the proper inflation will extend the life of your tires and will reduce the rolling resistance of your chair, making it easier to use. 1. Check your tires WEEKLY for proper inflation. The correct inflation level is imprinted on the tire sidewall. 2. DO NOT use your chair if any of the pneumatic tires are under-inflated or over-inflated. 3. If any tire is under-inflated, the chair may tend to veer to one side, which could cause you to lose control of the chair. 4. If a rear tire is under-inflated, the wheel lock for that wheel may not work properly and may slip, thereby allowing the wheel to turn unexpectedly. 5. An over-inflated tire may burst, thereby causing a loss of control of the chair. 6. ALWAYS have pneumatic tire inner tubes replaced by an authorized TiLite dealer. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. K. REAR WHEEL LOCKS I WARNING Standard rear wheel locks are available on all TiLite wheelchairs as a no-charge option. Scissor locks and uni-locks are optional equipment. TiLite wheel locks are NOT designed to slow or stop a moving wheelchair - they are NOT brakes. Wheel locks are ONLY designed to keep the rear wheels from rolling when your chair is at a complete stop. 1. NEVER attempt to “brake” by using rear wheel locks to try to slow or stop your chair when it is moving. If you do so, you will lose control of the chair and may fall. 2. ALWAYS make sure the locking arm of your wheel lock embeds into the tire at least 3/16” when in the locked position. If the wheel lock does not properly embed in the tire, the wheel lock may not work and the chair may roll unexpectedly. 3. ALWAYS maintain proper tire pressure. If a rear tire is under-inflated, the wheel lock for that wheel may not work properly and may slip, thereby allowing the wheel to turn unexpectedly. 4. When you transfer to or from your chair, ALWAYS set both rear wheel locks to prevent the rear wheels from rolling. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. L. PUSH HANDLES I WARNING Push handles are optional equipment on TiLite wheelchairs. Push handles provide secure points for an attendant or assistant to hold the rear of the chair to prevent a fall or tip-over. If you have an attendant or assistant, you should have push handles installed on your chair by TiLite. TiLite offers push handles that are integral to the back canes and bolt-on push handles. TiLite recommends that you do NOT use non-TiLite bolt-on push handles because they will damage the backrest of your TiLite chair. Your attendant or assistant should regularly check the push handle grips to make sure they fit securely and will not rotate or slip off. Push handles should NEVER be used to lift the chair or pull the chair, especially when it is occupied, as they may detach. ALWAYS lift or pull the chair by grasping a nondetachable part of the main frame (not the backrest, armrest or footrest). Aero T and TRA Owner’s Manual 1-15 OM0008_Rev A_Aero T_TRA CHAPTER 1: WARNINGS If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. M. FASTENERS I WARNING TiLite uses only high-strength, high-quality fasteners (nuts, bolts, screws and clamps) on its wheelchairs. If you replace any of these fasteners with improper or inferior fasteners, you may damage your chair or may cause it to fail unexpectedly. 1. ALWAYS use fasteners obtained from an authorized TiLite dealer. 2. REGULARLY inspect all fasteners to make sure they have not become loose. If any become loose, tighten them immediately. 3. NEVER over- or under-tighten the fasteners on your chair. Over-tightened or under-tightened fasteners may damage your chair or fail unexpectedly. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. N. POWER DRIVE I WARNING Certain manufacturers offer manual wheelchair power drive add-on products. TiLite has approved only a limited number of these products for use with TiLite wheelchairs. For more information about power add-ons approved by TiLite, contact TiLite Customer Service. If you intend to install an approved power drive system on your TiLite chair, this must be taken into account when your chair is ordered so TiLite can manufacture your chair with a power-adaptable frame. If you have not purchased your TiLite chair with a power adaptable frame, do not install a power drive on your TiLite chair. If you install a power drive add-on system to your TiLite chair and your chair does not have a power adaptable frame, you may damage your chair and you will void your warranty. In addition, power drive systems are heavy and will affect the center of balance of your chair. Any change to the center of balance of your chair could cause you to lose control or fall or tip-over. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. O. UNAUTHORIZED PARTS AND ACCESSORIES NEVER use parts, accessories or adapters other than those authorized by TiLite. If you have any doubt about the compatibility of a particular part, accessory or adapter, consult with an authorized TiLite dealer or contact TiLite Customer Service. If you ignore these Warnings, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair.

Cleaning often will reveal loose or worn parts and enhance the smooth operation of your chair. Cleaning the Frame 1. If your chair has a painted frame, use a soft clean cloth with soap and water to clean the frame. Immediately dry all components and parts that become wet. Note: Do NOT use Scotch Brite™ pads, steel wool, abrasive cleaners or petroleum-derived products to clean a painted aluminum or titanium frame. Cleaning the Upholstery 1. Regularly hand-wash the seat sling and back upholstery using water and a mild detergent. Always allow the upholstery to air dry before riding in the chair. 2. NEVER machine wash the upholstery, and NEVER machine dry the upholstery. 3. When washing the upholstery, carefully check for sagging, rips or tears. If you find any rips or tears, you MUST order new upholstery. 4. After washing the seat sling, always check the tension while seated in the chair to ensure the sling does not touch the crosstube beneath the seat sling. Axles and Moving Parts Clean axles and other moving parts weekly with a slightly damp, but not wet, cloth. Try to wipe away any lint, dust or dirt on these parts that could interfere with their smooth operation. DO NOT use WD-40®, 3-in-1 oil®, or other penetrating lubricants on quick-release or quad-release axles. Instead, as indicated in the chart under “Safety Inspections and Maintenance,” ALWAYS use either a “dry” Teflon®-based lubricant or a “dry“ silicone spray as a lubricant. Storage 1. Always store your chair in a clean, dry location. Excessive dirt can cause moving parts to become damaged or fail. Moisture can rust or corrode the non-titanium components of your chair. 2. Always fully inspect your chair after it has been stored for any period before riding in it. See the chart under “Safety Inspections and Maintenance” on pages 2-1 to 2-3. 3. If you store your chair for more than three (3) months, have your chair inspected by an authorized TiLite supplier. Aero T and TRA Owner’s Manual 2-3 OM0008_Rev A_Aero T_TRA CHAPTER 2: SAFETY INSPECTION, MAINTENANCE & TROUBLESHOOTING Troubleshooting Your TiLite wheelchair is a precision-engineered product.

If you ignore this Warning, the footrests could move unexpectedly while you are using the chair, causing you to fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. I WARNING A titanium open loop footrest is available as an option. A footrest cover is recommended for wheelchair users that have leg spasticity or whose feet have a possibility of falling through an open loop footrest. If you ignore this Warning, you could fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. I WARNING A calf strap is offered as an option with each wheelchair to prevent your feet from slipping backwards off of the footrest. TiLite recommends that you purchase our calf strap with your wheelchair. Always make sure the calf strap is secure when using the wheelchair. If you ignore this Warning, you could fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. I WARNING Whenever you adjust the angle or height of your footrest, or you replace your footrest, always allow at least 2” of ground clearance to permit you to maneuver over objects. If you ignore this Warning, you could fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Safe Tread If you ordered your wheelchair with either the Titanium Footrest with Flat ABS Cover or the Titanium Open Loop Footrest, enclosed with your chair are two 4” squares of self-adhesive Safe Tread. Safe Tread provides a more slipresistant surface than the footrest of your chair. Use of the Safe Tread is optional, but TiLite recommends you use it in order to reduce the likelihood of your feet slipping off the footrest during use of your chair. If you choose to apply the Safe Tread to your footrest, follow the following instructions: 1. See Figure 3-1 for the suggested location of the Safe Tread. 2. Without removing the adhesive backing strip, position the Safe Tread on the footrest and, if necessary, use a pen or pencil to draw any edges that need to be trimmed. 3. Carefully cut the Safe Tread to size using scissors, knife or razor blade. 4. Thoroughly clean and dry the footrest. 5. Peel the adhesive strip backing from the Safe Tread and press firmly to the surface of the footrest, starting from the center and working toward the edges of the Safe Tread, making certain the edges are fully adhered.

If you ignore this Warning, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Stainless and Titanium Quick-Release Axles Adjusting IWARNING Quick-Release Axles are pre-adjusted to permit minimal “play” in the axle. TiLite recommends that you do not adjust the axle. Improperly adjusting the axle could cause it to malfunction—too much “play” can cause the axle to bend and become stuck in the axle sleeve or Zero Play camber tube; too little “play” can prevent the locking balls from engaging fully, causing the wheel to disengage from the chair without warning. TiLite recommends that an authorized TiLite dealer make any adjustments. If you ignore this Warning, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair. Tools Needed: • 3/4” End Wrench • 7/16” End Wrench 1. Depress the release button and remove the rear wheel and Quick-Release Axle. See Figures 9-1 and 9-2. 2. Remove the axle from the wheel by depressing the release button and sliding the axle through the rear wheel hub. 3. Once removed from the hub, release the release button (the locking balls should be fully extended). 4. Increase or decrease axle play by adjusting the locknut while securing the opposite end of the axle using the smaller wrench at the flats at the end of the axle. 5. Depress the release button on the Quick-Release Axle and slide the axle through the rear wheel hub. 6. Depress the release button and reinstall the rear wheel into the axle sleeve or Zero Play camber tube. 7. Before riding in the chair, make sure the locking balls have fully secured the wheel in the axle sleeve or Zero Play camber tube by pulling on the hub without depressing the release button on the Quick-Release Axle. If the locking balls do not fully engage, repeat these procedures and increase the play (i.e., increase the distance between the locknut and the locking balls) to permit the locking balls to fully engage properly. Also, check to make sure there is not too much play in the axle.

Figure 11-3 Single-Sided Fork Fork Axle E-Ring Floating Casters Tools needed: • 3/16” Allen Wrench • Wood Block (1” Minimum) • Drafting Triangle • Ruler or Measuring Tape Note: TiLite designs its rigid wheelchairs to be flexible for improved maneuverability and increased ride comfort. However, this flexibility requires that your chair be set up properly. The following procedure will enable you to set up your TiLite rigid wheelchair so it will perform to its potential. 1. Place the wheelchair on a smooth, level surface with the casters trailing rearward. Aero T and TRA Owner’s Manual 11-3 OM0008_Rev A_Aero T_TRA CHAPTER 11: CASTERS AND FORKS 2. Before making any adjustments to the chair, it is important to check the following: a. The tires are properly inflated to the PSI rating shown on the sidewall of the tire. b. The camber tube is properly centered on the frame side to side and the camber tube is straight relative to the rear of the frame. For adjustments see “Replacing the Camber Tube” on page 8-3. c. The toe-in/toe-out is correctly set up (see “Adjusting Toe-In/Toe-Out” on pages 8-3 and 8-4). All items in this list are performed at the factory to ensure proper frame alignment before shipping. If an adjustment still needs to be made, complete it before proceeding. If no adjustment is needed, proceed to Step 3. 3. Loosen, but do not remove, the Allen screw in the footrest clamp only on the side of the floating caster as shown in Figure 11-5. Loosen the Allen screw sufficiently to permit the footrest to adjust up or down freely within the clamp. See “Titanium Footrest with Flat ABS Cover - Adjusting the Height/Replacing” on page 3-2. 4. If your chair has a bumper assembly, this assembly will need to be removed. Loosen, but do not remove, all of the Allen screws in the camber tube clamp on the side opposite the floating caster as shown in Figure 11-4. Do not loosen the two CG bracket Allen screws too much as it will allow the clamp to slide within the CG bracket. 5. Wiggle the chair and let it settle on to the flat surface to release any bind that may have existed within the chair assembly. 6. Make sure your footrest is set to your desired seat-to-footrest measurement, and, using a ruler or measuring tape, make sure the left and right sides of the footrest are the same distance from the level surface. It is important to have both sides of the footrest level and the footrest clamp screw tightened before the camber tube mount assemblies are tightened. 7. Tighten the footrest clamp screw. 8. Tighten the camber clamp screws starting with the uppermost screws and working downward. 9. If the above adjustments correct the floater and all four wheels are flat on the level surface, you are finished with your adjustment. If a caster is still floating, repeat Steps 3 through 8. If you continue to have a floater, proceed to Steps 10 through 13. 10. Loosen, but do not remove, the Allen screw in the footrest clamp only on the side of the floating caster as shown in Figure 11-5. Once the screw is loose and the full head of the screw is exposed, strike the Allen wrench with a mallet upward to release the internal wedge in the footrest clamp. See “Titanium Footrest with Flat ABS Cover Adjusting the Height/Replacing” on page 3-2. 11. Place a wood block under the other caster (which is not floating) as shown in Figure 11-6. 12. Apply gentle downward pressure on the caster mount of the floating caster. It is advisable that you have an assistant to place downward pressure on the opposite side of the chair at the backrest when making this adjustment. 13. Remove the wood block and check to see if the caster still floats. If the caster no longer floats, securely tighten the Allen screw on the footrest clamp. If the caster still floats, or if the other caster starts to float, check that the footrest is level and repeat Steps 10 through 13 until the caster no longer floats. 14. If the floater continues and cannot be corrected using these steps, please contact TiLite Customer Service.
